Police say Davis hit the woman on the right side of her head with a "covered hand." The woman had a facial injury, but she was able to leave the house after a quarrel. Davis was arrested about an hour after the alleged incident and charged with domestic violence.
Davis was released on $1,000 bail after being under arrest for one night.
Davis is scheduled to take on Hector Luis Garcia in a highly anticipated boxing match on January 7 in Washington, DC.
